The Preparation of Nanosized Iron Oxide Using Hydrolysis Enhanced by CuO and their Characterization

Abstract:

By adding CuO into heated Fe (NO₃)₃ aqueous solution, a precipitation reaction takes place to form nanosized iron oxide. The product obtained were characterized by transmission electron microscopy (TEM), vibrating sample magnetized (VSM), X-ray diffraction (XRD), energy disperse X-ray spectroscopy (EDX) and X-ray photoelectron spectroscopy (XPS). The experimental results showed that the product is weakly magnetic nanoclusters based on smaller ferrihydrite Fe₅O₇(OH)·4H₂O nanocrystallites. The nanoclusters are of about 40 nm size and absorbed by Fe (NO₃)₃. The experimental results are attributed to the Fe (NO₃)₃ hydrolysis reaction being enhanced by CuO as hydrolyte. A new route is proposed for the preparation of nanosized oxide using hydrolysis enhanced.
